Game Cache

Hey I was wondering if someone could post or make tutorial about.. Game Cache.
It should store following things:
1) Hero's Experience
2) Hero's Items
3) Hero's Skills

Game Cache - Initiallize game cache ("x")
Game cache - (last created game cache) store unit "mission" "unit" (the hero)

Game Cache - Save (last created gamecache)

then in another map


Game Cache - Initiallize game cache ("x")
Game cache - Restore from (last created game cache) "mission" "unit" at (position) for player facing.


voila, and yes, The hero's experience , items and skills are saved automatically with this.
